Earth economics studies the economy of our planet from the perspective of an autarkic system (a “closed economy”). It ignores the constituent national and regional parts of the planet economy and focuses on the whole. The book respects the heritages of IS/LM (Keynes) and neoclassical growth (Solow) not out of economic respect but because these tools are very useful in understanding the crisis and the policy response to that crisis.

377 - DNB Working PaDate 22 May 2013

We test the performance of various measures of global liquidity as early warning indicators of booms in house and equity prices in 20 OECD countries between 1970 and 2010. We use a panel probit approach to test the relative performance of global liquidity measures based on two aggregation schemes: the traditional measures, based on G5 data, and broader measures, based on data for up to 26 countries/currency areas.
Our results show that, in the last decade, global liquidity measures outperformed domestic measures as early warning indicators. Between the two global liquidity measures, G5 aggregates often outperformed broader global liquidity measures. The search for the best early warning indicator showed that the G5 real narrow money gap performed best for booms in house prices, while the global real private credit growth gap performed best for booms in equity prices, either when aggregated over G5 or over a broader sample of countries.
Nevertheless, given the rising importance of the emerging market economies and a declining share of G5 in global liquidity, the current superior performance of G5 measures may not warrant their superior performance in the future. Therefore, given the importance of global liquidity measures in warning about asset price booms, the need for constructing broader global liquidity measures is warranted.
